Biomimetic Oxidation of Sulfides Catalyzed by Polystyrene-Bound Dioxomolybdenum Complex as an Efficient Recoverable Heterogeneous Catalyst

In the present study, a dioxomolybdenum(VI) complex chelated with the ONO tridentate Schiff base ligand supported on chloromethylated polystyrene [MoO2L@CMP] was synthesized and characterized by various spectroscopic techniques like FT-IR, UV-Vis, DRS, SEM and EDAX. Then, its application was investigated in the oxidation of various alkyl and aryl sulfides using hydrogen peroxide in ethanol under reflux conditions. The supported catalyst could readily be recovered from the reaction mixture and reused several times with no considerable increase in its catalytic activity.
